I Have SQL Authentication But Can Connect To SQL DBs Without Being Asked To Log In. I Need To Change This.
Mar 13, 2008
Hello, I have several SQL 2000 logins on our servers. I removed the builtin/ groups and only have SQL authentication users, although the server is operating in "Mixed Mode". How can I secure this? I don't understand how we can just connect to any DB without ever being asked to log in. Let me know if you can help. Thanks.
I have a web app, designed using VWD Express and using SQL 2005 Express. It has a mdf database called "client". It was created using security of windows authentication. I have already changed my instance of sql server express to accept mixed windows and sql authentication. How do I change my "client" database's permissions to the sql authentication? I need to add a user name and password as a requirement for my web host to be able to attach the mdf to their instance of sql 2005. It has to be the same user and password as I use with my web host's sql server 2005. Thank you in advance.

Change the Authentication Mode of the SQL server from "Windows Authentication Mode (Windows Authentication)" to "Mixed Mode (Windows Authentication and SQL Server Authentication)".
I have instaled SQL Server2000 in Administrator user login.My OS is Windows Adavance Server2000. It works Fine. If i change my Administrator Password and Login with the new Password then Sql Server dosn't Run.It says Authentication error if i try to run from service. I belive DBA's in this forum can help me out.
Hello- I recently inherited a SQL 2005 Standard database that I am being asked to change the Server authentication mode for. SQL system is managing a local database for Microsoft Systems Management Server 2003. Currently the system is running in SQL Server & Windows authentication mode. I am going to change it to Windows Authentication mode. Can someone point me to a checklist I could refer to before I make the change to be sure I don't take down my database?
Hi,Does anyone here know whether it is possible to change theauthentication method of a SQL server instance programmatically, ratherthan going through enterprise manager.I am using SQL-DMO (under C#) for some other things, but thedocumentation is so bad that I can't find out whether what I want to docan be done. I have also tried googling but came up empty handed.I hope that someone can help me.CheersJono
I installed SQL Server 2005 using Windows Authentication Mode (Windows Authentication)"
How can I change the Authentication Mode of the SQL server from "Windows Authentication Mode (Windows Authentication)" to "Mixed Mode (Windows Authentication and SQL Server Authentication)"?
I have a login page that checks the given userid/password against ADSI and redirects the user if successful. My problem seems to come when I try to connect to the SQL database with the user's NT credentials. I have the user's NT account setup in SQL, have anony. disabled in IIS, using Integrated Windows Security in IIS, and am using the following connection string:
I also have this entry in my Web.Config file: <identity impersonate="true" />
Actually, it seems to connect OK, but I can not select any data. I just receive "Select permission denied...." errors even though the user has been given these permissions in SQL.
I am unable to connect to my local sql server express db. I would like to test my app and its not connecting. It works when I use windows authtentication Trusted_Connection=yes but not when i use: user id=sdvaid; password=sdavid
Dim conn As SqlConnection = New SqlConnection(connectionString) Dim cmd As SqlCommand = New SqlCommand("select * from Users", conn) cmd.CommandType = CommandType.Text Try conn.Open() cmd.ExecuteNonQuery() Catch ex As Exception Response.Write(ex.ToString()) Finally
conn.Close() End Try
thanks.
Here is the error: "SQL Server does not exist or access denied."
I want to distribute my sql server express database file ( .mdf ) with my application. The only connection I can use is the Windows Authentication but I need a Sql Server Authentication with which I can use a username and a password. I tried Sql Server Management Studio Express but no way Can anybody supply a step by step tutorial on how to achieve this? All the examlpes I could find in internet were using Windows Authentication, that's also interesting and painful Thanks for any help guys.
I have my SQL 7.0 server set for Mixed security. I see now (finally)the advantages of having windows authentication security for windowsgroups.I do most of my developing in Access Projects which require a login ofsome type. I have been using my SQL login to develop with SQL andthen when I give it to the user, I set the project to use Windowsauthentication. I want to be able to have Windows authentication onmy domain account but the user name for my windows account is the sameas my SQL account and it won't let me change the existing account.Now what happens is after I develop the product I have to have theuser login and go in and change to windows authentication. It won'tlet me do it with my sql account.I fear that if I delete my sql account and create a windowsauthentication account all the views, sps, etc. that I have createdwill still have the reference to the sql login and therefore not work.Do I need to have a generic sql account for developing? One thought Ihad was to create a new domain account so I can create that windowslogin and at least get my most recent projects working like I want to?Hope this makes sense to someone.Thanks in advance for your time.Sherry
We are experiencing authentication/ Kerberos issues after a password for the MSA's has changed. We use MSA for our SQL 2012 and windows 2012 combination Servers. This errors creates issues while backing up and Service Broker connectivity.We had to restart sql services to fix it, but this not seem to be a resolution for me because the next time the password changes on these MSA's we may have to restart sql services.There seems to be a known issue for windows 2008 R2 servers and fix is available and we incorporated it. But the issue we are facing is on windows 2012 Server.
Just spoke w/ our network admin and he mentioned that we use SPI, so being brand new to ASP, i did some googling and found this string:
the username and password is the account i have for the database, which is windows authentication, so i made sure the domain was in there. i am unsure of what i am doing wrong.
Hello , i m new to SQL Server when i am connecting it shows me error "An error has occured while establishing a connection to the server.When connecting to SQL Server 2005,this faliure may be caused by the fact that under the default settings SQL Server does not allow remote connections.(provider: SQL Network Interfaces,error:26-Error Locating Server/Instances Specified)(Microsoft SQL Server)"
please help me as soon as possible, Thanks in advance
I'm trying to connect to a database using my virtual machine, where I´m logged in as another user than the one that's granted acccess to the database. Can I enter the windows username and password used to connect to my SQL 2005 database, in Windows Authentication Mode?
hi guys, do you know if we can use sql authentication to connect to SSIS through SSMS. right now it's only windows authentication, and SQL authentication is grayed out.
Not sure if this question has already been answered because it sounds like easy question.
Hi all, I've read up on the fact that if you use SQL server 2005 instead of SQL express you need to change the connection string in web.config. Is there anyway to make this default connection type, or do I have to do it for every website I create. i.e. is there a global file that this connection can be entered into. Then whenever I start a new website I don't have to put the string in. Just me being lazy really. But it's nice to know if it's possible.
I have made a small asp.net project which uses a local database file as a part of the project. The project is running fine om my local machine, but when I upload it to the remote server, the login fails for the server.
I suspect this is can be solved by using sqlserver authentication. But I have now spent a lot of time trying to configure the database file to use this authentication mode. As I see it there are three possible solutions to the problem.
use management studio express to configure the local mdf file (Ecxept that I cant find out how to connect to the mdf-file) and from here change the authentication method to sqlserver authentication. use Visual Web developer to change the authentication method (but how???) make the windows authentication work on the server (this would probably require that mannamgement studio express connects to the remote database. (Same problem as no 1)
I use the Mangement Studio Express to manage a MSDE 2000 instance and notice that the Server authentication area in the Security is disabled for that instance. But for an Express instance, the Server authentication area is enabled. Is this difference caused by some settings?
I am not able to connect to SQL Database server using windows authentication when I am connected through VPN connection.However I am able to connect to same server using SQL server authentication and also able to do RDP to DB server machine.
I found a resolution in one of the forum suggesting to change UserRasCredentials to 0 value in *.pdk file.Since VPN connection which I am using generates instant proxy this resolution doesn't work.
Also application which I am using does windows authentication connection it is required for me to impersonate windows authetication when connected using VPN.
I created a HTTP-Endpoint on SQL Server 2005. Now I try to call this web service from a c# client but using SQL-Server authentication (i.e. my user is a sql server user but not a windows user). But it doesn't work. I can connect to the service using a windows user and NTLM authentication. But for some reasons Iwould much prefer if I could use SQL-Server authentication. Is it possible?
Here is how I created the endpoint:
Code Snippet CREATE ENDPOINT myService STATE = STARTED AS HTTP( PATH = '/services', AUTHENTICATION = (INTEGRATED ), PORTS = ( SSL ), SITE = '*' ) FOR SOAP ( WEBMETHOD 'GetStuff' (name='MyDB.dbo.FKT_getStuff', SCHEMA=STANDARD ), WSDL = DEFAULT, LOGIN_TYPE = MIXED, SCHEMA = STANDARD, DATABASE = 'MyDB', NAMESPACE = 'Services' ); GO
This morning I attempted to connect to my local copy of SQL Server (2012) (Win 7) using Windows Authentication. I was unable to do so and per the error log it was due to error 18456 (invalid credentials).
Yesterday I changed my windows password. Is it possible for this to be the cause?
FYI, following is from the error logs:

The logs showed the error occurred yesterday (4/28) which is about when I changed my password. The 17:09 log (last one) is when I shut down my computer. Note that I was logged into SQL Server when I changed my Windows password and worked with it several times through out the day.
Also, per the configuration manager SQL Server (MSSQLSERVER) (and all other services) is stopped and I was unable to start it ("The request failed or the service did not respond in a timely fashion).
Can someone point me at an article that tells how to allow the ASP.net worker process to connect, via windows authentication, to a remote sql server instance ?
We have SQL server 2000 on windows 2000. From our desktop MS Access was connected to database through ODBC. Since yesterday (after our consultant had updated another asp application in the same server) we are getting €œSQL Server Error: 18452. €¦.. Login failed for user €˜(null)€™. Reason: not associated with a trusted SQL Server connection. €œ
The consultant saying he did not touch any settings on server (?). And the problem is even server€™s security property shows it has mixed mode authentication. But I cannot connect to server even through my SQL server enterprise manager in windows authentication mode. I can connect if I use SQL server authentication. Through ODBC I can connect also and test fine, if I use SQL authentication. But the Access application wouldn€™t connect using SQL authentication in ODBC.
So, can any one help me to find out what else could be done to make sure that the server is going to accept windows authentication. I€™m thinking any other settings or registry change €¦ etc. Please help.
We need to use SQL Server Authentication for some reason and would like to enforce Password Policy with 90-day expiration period. I found "Change password" dialogue appears when I first logged in with the new user, but don't know
(1)what happens when the user failed to change the password before it's expired or (2)how a user can change his password in advance of the expiration date with no particular server-level permission.
We have see login failures for windows accounts. Below is the error message.
Description: In our env most logins are windows accounts. Initially we thought it is an UAC issue and we tried to launch the SSMS using "Run as Administrator". However, we are seeing login failures.
Enviroment: Microsoft SQL Server 2014 - 12.0.2402.0 (X64) RTM Enterprise Edition (HyperVisor)
Error Message in Error Log :

We tried dropping this account and re-creating the windows account with same permissions but still result is same. It throws same error message. Login failure message !!!
I need to change the authentication mode from 'windows' to mixed, its a 4-node participating in always-on... Will this brake/impact alwayson in any way? I know I have to restart the sql instance.
I am just about ready to tear my hair out on this one, at this point you guys are my last resort! Wouldn't it be nice if I could go to bed and have an answer for me in the morning....
I've had a working HTTP endpoint using Basic Authentication over SSL for months in our development environment, but now I'm moving our application to a production server and I'd like to be able to use Digest Authentication in the clear instead so the processor doesn't waste cycles on the SSL decryption. I've spent hours fiddling with my endpoint to no avail.
This is the closest message relating to what I'm doing that I've been able to find: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1131251&SiteID=1
In my case, the SQL Server is joined to a domain that is entirely Windows Server 2003 - no Windows 2000, so support for Digest Authentication is a non-issue. I'm also explicitly doing a GRANT CONNECT on my endpoint to the domain user I'm using. Here is the top of my CREATE ENDPOINT DDL:
I am debugging using wfetch 1.3... I can get this to work using NTLM Authentication; sending a GET to my endpoint with the ?wsdlsimple querystring parameter returns my WSDL just fine.
But Digest just doesn't want to work! If I remove NTLM from my AUTHENTICATION directive and try using Digest with wfetch or from my (PHP) web service consumer I get an HTTP 401 no matter what I do. I've tried fiddling with the DEFAULT_LOGON_DOMAIN, AUTH_REALM, and anything else I can think of.
The errors I am sporadically finding in the SQL Server error log are:
HTTP authentication failed. [CLIENT: 192.168.245.238] from source Logon
Followed by:
Error: 26026, Severity: 14, State: 1. from source Logon
I can't find any detail about the second error.
........
Just occurred to me that I've also been trying to view my WSDL directly in IE, and this is what's causing the SQL error to be logged, not wfetch - that's why it appeared sporadically.
So, wfetch isn't causing an 'HTTP authentication failed' error, but Internet Explorer is... maybe Digest Authentication isn't implemented correctly in wfetch?
Regardless... I'm still not able to authenticate from IE or from my client, but this may shed some more light on the issue.
